BACKGROUND

Soybean (Glycine max) is a major grain crop valued for the high levelsof oil and protein found in soybean seed. Soybean breeding has resultedin significant improvements in yield potential, stability of yield,adaptation of the species to mechanical harvest, and yield protectionthrough improved disease resistance.

Due to the nature of plant science agriculture, broadly defined as amanipulation of available plant resources to meet the needs of thegrowing human population, the environment in which plants are grown foragricultural production continuously offers new obstacles toagricultural production. Each new variety, or cultivar, released toagricultural production is selected for the purpose of increasing yieldresulting from increased disease resistance to prevalent diseases, orfrom direct or indirect improvement in yield potential or efficiency ofproduction. Development of stable, high yielding varieties with superiorcharacteristics is an ongoing goal of soybean breeders.

There is a need in the art for a novel, superior soybean variety andsoybean seed.

DETAILED DESCRIPTION

In the claims, descriptions, and tables that follow, numerous terms areused and are defined as follows:

Brown Stem Rot (BSR) caused by the fungus, Phialophora gregata, isvisually scored from 1 to 9 based on the severity of interveinal leafchlorosis (yellowing) and necrosis of stems. A score of 1 indicates themost resistance (no symptoms) and a score of 9 indicates the mostsusceptible.

Canopy width is measured at the widest point of the soybean plant.Visually scored from 1 to 9, where 1=very narrow canopy and 9=extremelybushy canopy.

Cotyledon is a type of seed leaf. The cotyledon contains the foodstorage tissues of the seed. Cotyledon color can be measured as acharacteristic of a variety.

Flower color: Modern soybeans are characterized by two major flowercolors, purple or white. Some varieties are heterogeneous for flowercolor whereby some plants have purple flowers and some have white.

Growth habit refers to stem termination in soybeans and the resultantdifferences in flower production. “Indeterminate” varieties continue togrow during the reproductive phase, producing new branches and nodesafter flowering is well underway. “Determinate” varieties tend to delaythe onset of flowering somewhat, and limit new node and branchdevelopment after flowering has been initiated. “Semi-determinate”varieties continue to produce new vegetative growth during thereproductive phase but growth terminates more quickly than inindeterminate varieties.

Hilum refers to the point of attachment of soybean seed to maternaltissue.

Hilum color in modern soybeans may be black, brown, yellow, gray, buff,or imperfect black.

Iron-Deficiency Chlorosis (IDC) results when soybeans lack adequateiron. A visual score taken 25 to 30 days after planting is used to rateiron-deficiency chlorosis. A score of 1 indicates no stunting of theplants or chlorosis of the leaves, and a score of 9 indicates the plantsare dead or dying as a result of iron-deficiency chlorosis. A score of4.5 means plants have intermediate health with some leaf chlorosis.

Leaflet shape: The leaflet may be broad or narrow and may be lanceolate,ovate or oval in shape.

Lodging relates to the stature of the plant relative to the ground.Lodging resistance is rated on a scale of 1 to 5. A score of 1 is givento an erect plant (lodging resistant). A score of 3 is given to a plantthat is leaning at a 45-degree angle relative to the ground. A score of5 indicates a plant lying on the ground.

Maturity date is the date when 95% of pods have turned color from greencolor to their mature brown or tan color. The maturity date is countedin days and is calculated from January 1.

Maturity group refers to an industry division of groups of varietiesbased on the zones in which the varieties are adapted. Soybeans maturedifferentially in response to day-length and thus to latitude wheregrown. In the soybean production areas of the United States, forexample, the northernmost production region of northern Minnesota isplanted to soybeans that mature under very long day-lengths during earlysummer. In the southernmost production regions of the Southeast,soybeans that mature from the influence of short day-length during earlysummer are grown. Those adapted to northern day-lengths are classifiedas early-maturing, those adapted to the southern regions are classifiedas late-maturing. Maturity groups include very long day length varieties(000, 00, 0) and extend to very short day length varieties (VII, VIII,IX, X). For example, maturity group I soybean varieties are typicallygrown in southern Minnesota, whereas maturity group IV soybean varietiesare typically group in southern Illinois.

Phytophthora “Root Rot” tolerance caused by the fungus, Phytophthoramegasperma var. sojae, is rated on a visual scale of 1 to 9, with ascore of 1 being the most tolerant and a score of 9 s being the mostsusceptible to Phytophthora. The visual score is based on the amount ofdisease-induced stunting of above-ground growth and is taken at harvest.

Plant includes plant cells, plant protoplasts, plant cell tissuecultures from which soybean plants can be regenerated, plant calli,plant clumps, and plant cells that are intact in plants or partsthereof. “Plant part” includes, but is not limited to, embryos,protoplasts, cells, pollen, ovules, cotyledons, hypocotyls, meristems,roots, pistils, anthers, flowers, stems, leaves, pods, petioles, and thelike.

Plant height is measured from the top of soil to top node of the plantin any convenient unit of length (i.e., inches, centimeters, etc.). Forthe data presented herein, plant height was measured just prior toharvest and is expressed in centimeters.

Pod wall color refers to the color of the mature pod wall, as distinctfrom the color of the pubescence, and in modern soybeans, may be brownor tan.

Pubescence relates to the plant trichomes or hairs found on the stems,leaves and pods of soybeans.

Pubescence color in modern soybeans may be tawny, gray or light tawny.

Relative maturity, within maturity groups, is a more precise maturityassignment that subdivides each maturity group into tenths. For example,a relative maturity of 3.3 is assigned to a late early maturity groupIII soybean variety.

Roundup Ready 2 tolerance refers to the transgenic soybean eventMON89788 from Monsanto Company, as identified in the USDA petitionextension No 06-1′780-01p, which imparts glyphosate tolerance to theplant.

Seed coat color refers to the color of the seed coat, and in modernsoybeans may be yellow, green, brown or black.

Seed coat luster refers to the luster of the seed coat, and may be dullor shiny.

Seed coat peroxidase activity is defined by a chemical taxonomictechnique to separate varieties based on the presence or absence of theperoxidase enzyme in the seed coat. There are two types of soybeanvarieties, those having high peroxidase activity and those having lowperoxidase activity. Ratings are HIGH or LOW for peroxidase enzymeactivity.

Seed size is measured by seed number per pound of seed. Seed size is aheritable trait but is influenced by environment, and as such, is oftenpresented as a comparison to another variety.

Shattering refers to pod dehiscence prior to harvest resulting in a lossof mechanically harvestable seed. Pod dehiscence involves seeds fallingfrom the pods to the soil. This is visually scored with a 1 to 9 scalecomparing all genotypes within a given test. A score of 1 means podshave not opened and no seeds have fallen out. A score of 5 indicatesapproximately 50% of the pods have opened, with seeds falling to theground and a score of 9 indicates 100% of the pods are opened.

Soybean Cyst Nematode (SCN) resistance is based on a comparison ofreproduction rates of Heterodera glycines to a known susceptible varietyas described by Schmitt et al. (Crop Sci. 32:275-277, 1992), which isincorporated by reference herein. A variety with a 0% to 10%reproductive rate compared to a known susceptible variety is classifiedas resistant (R); a variety with an 11% to 30% reproductive ratecompared to a known susceptible variety is classified as moderatelyresistant (MR); a variety with an 31% to 59% reproductive rate comparedto a known susceptible variety is classified as moderately susceptible(MS).

Soybean emergence scores, also referred to simply as “Emergence,” ratethe ability of the seedlings to emerge from the soil. A visual score of1 to 9, taken from emergence to V3, is used whereby a score of 1 to 3indicates excellent emergence vigor and early growth, an intermediatescore of 5 indicates average ratings, and a score of 7 to 9 indicates avery poor emergence vigor and early growth.

Sulfonylurea Tolerance is a herbicide-tolerance trait that improvessoybean tolerance to ALS (acetolactate synthase) inhibitor herbicides.Sulfonylurea Tolerant soybeans carry a modified ALS gene, which enhancesthe variety's natural tolerance to sulfonylurea.

Yield refers to the yield of seed harvested from a soybean crop. Yielddata presented herein is expressed as bushels of seed/acre and is theactual yield of the grain at harvest.

The present invention provides methods for producing soybean seed, orplants grown therefrom, by crossing the soybean variety SM14299337 withitself or a second variety. These methods can be used for propagation ofthe soybean variety SM14299337, or can be used to produceSM14299337-derived hybrid soybean seeds and the plants grown therefrom.Hybrid soybean plants can be used in the commercial production of soyproducts or may be advanced in certain breeding protocols for theproduction of additional novel soybean varieties by crossing the soybeanvariety SM14299337-derived soybean plant with itself or another soybeanplant to yield an additional soybean variety SM14299337-derived soybeanprogeny seed. This crossing process can be repeated one or more times togenerate additional soybean varieties. A hybrid plant can also be usedas a recurrent parent at any given stage in a backcrossing protocolduring the production of the soybean variety SM14299337 which comprisesan added desired trait.

In some embodiments, the present invention provides for using theSM14299337 soybean plant, or part thereof, or a soybean plant having thephysiological and morphological characteristics of the SM14299337soybean plant, as a source of breeding material for developing anSM14299337-derived soybean plant in a soybean breeding program usingplant breeding techniques. Plant breeding techniques useful in thedeveloping soybean plants include, but are not limited to, single seeddescent, modified single seed descent, recurrent selection, reselection,mass selection, bulk selection, backcrossing, pedigree breeding,mutation breeding, restriction fragment length polymorphism enhancedselection, genetic marker enhanced selection, making double haploids andtransformation. Plant breeding techniques are known to the art and havebeen described in the literature. For example, see U.S. Pat. Nos.6,143,954; 7,803,996; and 7,807,884, which, along with the referencescited therein, is incorporated by reference herein.

Selection of soybean plants for breeding is not necessarily dependent onthe phenotype of a plant and instead can be based on geneticinvestigations. For example, one may utilize a suitable genetic markerwhich is closely genetically linked to a trait of interest. One of thesemarkers may therefore be used to identify the presence or absence of atrait in the offspring of a particular cross, and hence may be used inselection of progeny for continued breeding. This technique may commonlybe referred to as “marker assisted selection.” Any other type of geneticmarker or other assay which is able to identify the relative presence orabsence of a trait of interest in a plant may also be useful forbreeding purposes. Procedures for marker assisted selection applicableto the breeding of soybeans are well known in the art. Such methods willbe of particular utility in the case of recessive traits and variablephenotypes, or where conventional assays may be more expensive, timeconsuming or otherwise disadvantageous. Types of genetic markers whichcould be used in accordance with the invention include, but are notnecessarily limited to, Simple Sequence Length Polymorphisms (SSLPs),Restriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF),Sequence Characterized Amplified Regions (SCARs), Arbitrary PrimedPolymerase Chain Reaction (AP-PCR), Amplified Fragment LengthPolymorphisms (AFLPs) (EP 534 858, specifically incorporated herein byreference in its entirety), Simple Sequence Repeats (SSRs, also referredto as “Microsatellites”), and Single Nucleotide Polymorphisms (SNPs).

Many qualitative characters also have potential use as phenotype-basedgenetic markers in soybeans; however, some or many may not differ amongvarieties commonly used as parents. The most widely used genetic markersare flower color (purple dominant to white), pubescence color (browndominant to gray), and pod color (brown dominant to tan). Theassociation of purple hypocotyl color with purple flowers and greenhypocotyl color with white flowers is commonly used to identify hybridsin the seedling stage. Differences in maturity, height, hilum color,pubescence color, pod wall color, and pest resistance between parentscan also be used to verify hybrid plants.

Soybean variety SM14299337 represents a novel base genetic variety intowhich a new desired locus or trait may be introduced by introgression.Backcrossing and direct transformation represent two important methodsthat can be used to accomplish such an introgression. In certainembodiments of the present invention, plants of soybean varietySM14299337 are provided modified to include one or more desiredheritable traits.

Plants of the subject invention including one or more desired heritabletraits may, in one embodiment, be developed by a plant breedingtechnique called backcrossing, wherein essentially all of the desiredphysiological and morphological characteristics of a variety arerecovered, when grown in the same environmental conditions, in additionto a genetic locus comprising the desired trait transferred into theplant via the backcrossing technique. Backcrossing methods can be usedwith the present invention to improve or introduce a desired trait intosoybean variety SM14299337. The parental soybean plant which contributesthe locus for the desired characteristic is termed the nonrecurrent ordonor parent. This terminology refers to the fact that the nonrecurrentparent is used one time in the backcross protocol and therefore does notrecur. The parental soybean plant (e.g., soybean variety SM14299337) towhich the locus or loci from the nonrecurrent parent are transferred isknown as the recurrent parent as it is used for several rounds in thebackcrossing protocol (Poehlman et al., 1995; Fehr, 1987a,b; Sprague andDudley, 1988).

In a typical backcross protocol, the original variety of interest(recurrent parent, e.g., soybean variety SM14299337) is crossed to asecond variety (nonrecurrent parent) that carries the single locus ofinterest to be transferred to produce F1 progeny plants. The resultingF1 progeny from this cross are then selected that have the desired traitand crossed again to the recurrent parent to produce backcross progenyplants having the desired trait and physiological and morphologicalcharacteristics of the recurrent parent. The process is repeated until asoybean plant is obtained wherein essentially all of the desiredmorphological and physiological characteristics of the recurrent parentare recovered in the converted plant, in addition to the transferredlocus comprising the desired trait from the nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single or a very limited number of traits orcharacteristics into the original variety. To accomplish this, a singlelocus of the recurrent variety is modified or substituted with thedesired locus from the nonrecurrent parent, while retaining essentiallyall of the rest of the desired genetic, and therefore the desiredphysiological and morphological constitution of the original variety.The choice of the particular nonrecurrent parent will depend on thepurpose of the backcross; one of the major purposes is to add somecommercially desirable, agronomically important trait to the plant. Theexact backcrossing protocol will depend on the characteristic or traitbeing altered to determine an appropriate testing protocol. Althoughbackcrossing methods are simplified when the characteristic beingtransferred is a dominant allele, a recessive allele may also betransferred. In this instance it may be necessary to introduce a test ofthe progeny to determine if the desired characteristic has beensuccessfully transferred.

Soybean varieties can also be developed from more than two parents(Fehr, In: Soybeans: Improvement, Production and Uses, 2d Ed., Manograph16:249, 1987). The technique, known as modified backcrossing, usesdifferent recurrent parents during the backcrossing. Modifiedbackcrossing can be used to replace the original recurrent parent with avariety having certain more desirable characteristics or multipleparents may be used to obtain different desirable characteristics fromeach.

Many single locus traits have been identified that are not regularlyselected for in the development of a new inbred but that can be improvedby backcrossing techniques. Single locus traits may or may not betransgenic; examples of these traits include, but are not limited to,male sterility, herbicide tolerance, insect resistance, modified fattyacid metabolism, modified carbohydrate metabolism and resistance tobacterial disease, fungal disease or viral disease.

Direct selection may be applied where the single locus acts as adominant trait. An example of a dominant trait is an herbicide tolerancetrait. For this selection process, the progeny of the initial cross aresprayed with the herbicide prior to the backcrossing. The sprayingeliminates any plants which do not have the desired herbicide tolerancecharacteristic, and only those plants which have the herbicide tolerancegene are used in the subsequent backcross. This process is then repeatedfor all additional backcross generations.

In other embodiments of the present invention, plants of the subjectinvention including one or more desired heritable traits may bedeveloped by direct transformation of soybean variety SM14299337, orthrough the use of backcrossing approaches as described herein, forexample, to introgress a transgenic trait into soybean varietySM14299337. Accordingly, in one embodiment of the present invention amethod of producing a plant of soybean variety SM14299337 comprising anadded desired trait is provided, where the method comprises introducingat least one transgene conferring the desired trait into varietySM14299337. In some embodiments, introducing at least one transgeneconferring the desired trait comprises transforming a soybean plant, orpart thereof, of variety SM14299337 with one or more transgenes thatconfer at least one desired trait. In another embodiment, introducing atleast one transgene conferring the desired trait comprises use ofbackcrossing to introgress a transgenic trait into soybean varietySM14299337. Another embodiment is the product produced by this process,wherein the product comprises the at least one desired trait and all ofthe physiological and morphological characteristics of soybean varietySM14299337 when grown in the same location and in the same environmentalconditions.

In one embodiment the desired trait may be one or more of malesterility, site-specific recombination, abiotic stress tolerance,herbicide tolerance, insect or pest resistance, disease resistance,fungal resistance, modified fatty acid metabolism, and modifiedcarbohydrate metabolism. The specific gene may be any known in the artor listed herein, including: a polynucleotide conferring tolerance toglyphosate, phenoxyacetate auxins, pyridyloxyacetate auxins,phenoxyproprionate auxins, phenoxybutanoate auxins, sulfonylurea,imidazalinone, dicamba, glufosinate, cyclohexone, triazine, andbenzonitrile; a polynucleotide encoding a Bacillus thuringiensispolypeptide (e.g. Cry1F and/or Cry1Ac), a polynucleotide encodingphytase, FAD-2, FAD-3, galactinol synthase or a raffinose syntheticenzyme; or a polynucleotide conferring resistance to soybean cystnematode, brown stem rot, phytophthora root rot, soybean mosaic virus orsudden death syndrome.

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to: genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences. Forexample, see the traits, genes and transformation methods listed in U.S.Pat. No. 6,118,055. The most prevalent types of plant transformationinvolve the construction of an expression vector. Such a vectorcomprises a DNA sequence that contains a gene under the control of oroperatively linked to a regulatory element, for example a promoter. Thevector may contain one or more genes and one or more regulatoryelements.

Plant transformation techniques which result in the generation oftransgenic plants are known in the art. These techniques include, butare not limited to:

(1) Projectile bombardment or microprojectile-mediated delivery. Thisprocedure involves propelling inert or biologically active particlescomplexed with DNA at plant cells, wherein the particles penetrate theouter surface of the cell and the DNA is incorporated within the genomeof the plant cell.

(6) Agrobacterium-mediated transformations of plants are also included.Agrobacterium-mediated transformation is described in, for example,Horsch et al., (1984) Science 233:496-498, and Fraley et al., (1983)Proc. Nat. Acad. Sci. USA 80:4803 and U.S. Pat. Nos. 5,824,877;5,981,840, and 6,384,301; Ishida et al., (1996) Nature Biotechnology14:745-750. Generally, the Agrobacterium transformation system is usedto engineer dicotyledonous plants see Bevan et al (1982) Ann. Rev. Genet16:357-384; Rogers et al., (1986) Methods Enzymol. 118:627-641). TheAgrobacterium transformation system may also be used to transform, aswell as transfer, DNA to monocotyledonous plants and plant cells. SeeU.S. Pat. No. 5,591,616; Hemalsteen et al., (1984) EMBO J3:3039-3041;Hooykass-Van Slogteren et al., (1984) Nature 3 11: 763-764; Grimsley etal., (1987) Nature 325: 1677-179; Boulton et al., (1989) Plant Mol.Biol. 12:3 1-40.; and Gould et al., (1991) Plant Physiol. 95:426-434. Inaddition, gene transfer may be achieved using non-Agrobacterium bacteriaor viruses such as Rhizobium sp. NGR234, Sinorhizobium meliloti,Mesorhizobium loti, potato virus X, cauliflower mosaic virus and cassavavein mosaic virus and/or tobacco mosaic virus, See, e.g., Chung et al.,(2006) Trends Plant Sci. 1 1(1): 1-4; U.S. Pat. Nos. 6,660,500,6,462,255, 5,889,190 and 5,889,101.

Soybean transformation is described in particular in a number ofpublications. An example of an exemplary soybean transformationtechnique includes the use of Agrobacterium-mediated planttransformation. One example of soybean transformation comprisesinfecting half-seed explants of soybean with Agrobacterium tumefacienscontaining a transgene and regenerating the half-seed explants in vitroon selection medium. See U.S. Pat. No. 7,473,822 and Paz et al., (2006)Plant Cell Reports 25: 206-213. A second example ofAgrobacterium-mediated soybean transformation employs the use ofglufosinate as the selection system, thereby resulting in an enhancedtransformation efficiency. See Zeng et al., (2004) Plant Cell Rep22:478-482.

After effecting delivery of exogenous DNA to recipient cells, the nextsteps generally concern identifying the transformed cells for furtherculturing and plant regeneration. In order to improve the ability toidentify transformants, one may desire to employ a selectable orscreenable marker gene with the transformation vector used to generatethe transformant. In this case, the potentially transformed cellpopulation can be assayed by exposing the cells to a selective agent oragents, or the cells can be screened for the desired marker gene trait.

Cells that survive the exposure to the selective agent, or cells thathave been scored positive in a screening assay, may be cultured in mediathat supports regeneration of plants. In some embodiments, any suitableplant tissue culture media (e.g., MS and N6 media) may be modified byincluding further substances, such as growth regulators. Tissue may bemaintained on a basic media with growth regulators until sufficienttissue is available to begin plant regeneration efforts, or followingrepeated rounds of manual selection, until the morphology of the tissueis suitable for regeneration (e.g., at least 2 weeks), then transferredto media conducive to shoot formation. Cultures are transferredperiodically until sufficient shoot formation has occurred. Once shootsare formed, they are transferred to media conducive to root formation.Once sufficient roots are formed, plants can be transferred to soil forfurther growth and maturity.

To confirm the presence of a transgene in the regenerating plants, avariety of assays may be performed. Such assays include, for example:molecular biological assays, such as Southern and Northern blotting andPCR; biochemical assays, such as detecting the presence of a proteinproduct, e.g., by immunological means (e.g., ELISA and/or Western blots)or by enzymatic function; plant part assays, such as leaf or rootassays; and analysis of the phenotype of the whole regenerated plant.

Through the transformation of soybean, the expression of genes can bealtered to enhance disease resistance, insect resistance, herbicidetolerance, agronomic, grain quality and other desired traits.Transformation can also be used to insert DNA sequences which control orhelp control male-sterility. DNA sequences native to soybean as well asnon-native DNA sequences can be transformed into soybean and used toalter levels of native or non-native proteins. Various promoters,targeting sequences, enhancing sequences, and other DNA sequences can beinserted into the genome for the purpose of altering the expression ofproteins. Reduction of the activity of specific genes (also known asgene silencing, or gene suppression) is desirable for several aspects ofgenetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook ch.118 (Springer-Verlag 1994) or other genetic elements such as a FRT, Loxor other site specific integration site, antisense technology (see,e.g., Sheehy et al.

(1993) Antisense Res. Dev. 3:253);oligonucleotide-mediated targeted modification (e.g., WO 03/076574 andWO 99/25853); Zn-finger targeted molecules (e.g., WO 01/52620; WO03/048345; and WO 00/42219); and other methods or combinations of theabove methods known to those of skill in the art.

4. Genes that Control Male-Sterility.

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations asdescribed by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068,describe a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

(A) Introduction of a deacetylase gene under the control of atapetum-specific promoter and with the application of the chemicalN-Ac-PPT (WO 01/29237).

Soybean Products

Soybean is useful not only as a seed for producing soybean plants, butalso has utility as a grain. The grain can be used as a food source forboth animals and humans. Soybean is widely used as a source of proteinfor animal feeds for poultry, swine and cattle. The soybean grain istherefore a commodity. The soybean commodity plant products include butare not limited to protein concentrate, protein isolate, soybean hulls,meal, flower, oil and the whole soybean itself.

During processing of whole soybeans, the fibrous hull is removed and theoil is extracted. The remaining soybean meal is a combination ofcarbohydrates and approximately 50% protein. For human or animalconsumption soybean meal is made into soybean flour that is processed toprotein concentrates used for meat extenders or specialty pet foods.Production of edible protein ingredients from soybean offers a healthyless expensive replacement for animal protein in meats as well asdairy-type products.

Accordingly, the present invention includes in some embodiments methodsfor producing a commodity plant product, which comprise obtaining seedof soybean variety SM14299337 and producing the commodity plant productsdisclosed above. The invention further comprises soybean commodity plantproducts derived from soybean variety SM14299337 seed according to thesemethods.
